Referring to FIG. 1, the A/V (audio/video) input unit 120 receives anaudio or video signal, and the A/V (audio/video) input unit 120 mayinclude a camera 121 and a microphone 122. The camera 121 processesimage frames, such as still or moving images, obtained by an imagesensor in a video phone call or image capturing mode. The processedimage frame may be displayed on a display unit 151.

The image frames processed by the camera 121 may be stored in the memory160 or transmitted to an external device through the wirelesscommunication unit 110. Furthermore, the user's location information orthe like may be produced from image frames acquired from the camera 121.Two or more cameras 121 may be provided according to the useenvironment.

The microphone 122 receives an external audio signal through amicrophone in a phone call mode, a recording mode, a voice recognitionmode, and the like, and processes the audio signal into electrical voicedata. The processed voice data may be converted and output into a formatthat is transmittable to a mobile communication base station through themobile communication module 112 in the phone call mode. The microphone122 may implement various types of noise canceling algorithms to cancelnoise generated in a procedure of receiving the external audio signal.

The user input unit 130 may generate input data to control an operationof the terminal. The user input unit 130 may be configured by includinga keypad, a dome switch, a touch pad (pressure/capacitance), a jogwheel, a jog switch, and the like.

The sensing unit 140 detects a current status of the mobile terminal 100such as an opened or closed configuration of the mobile terminal 100, alocation of the mobile terminal 100, a presence or absence of usercontact with the mobile terminal 100, an orientation of the mobileterminal 100, an acceleration/deceleration of the mobile terminal 100,and the like, so as to generate a sensing signal for controlling theoperation of the mobile terminal 100. For example, when the mobileterminal 100 is a slide phone type, the sensing unit 140 may sensewhether a sliding portion of the terminal is open or closed. Otherexamples include sensing functions, such as the sensing unit 140 sensingthe presence or absence of power provided by the power supply unit 190,the presence or absence of a coupling between the interface unit 170 andan external device.

The output unit 150 is configured to generate an output associated withvisual sense, auditory sense or tactile sense, and may include a displayunit 151, an audio output module 153, an alarm unit 154, a haptic module155, and the like.

The display unit 151 may display (output) information processed in themobile terminal 100. For example, when the mobile terminal 100 is in aphone call mode, the display unit 151 may display a User Interface (UI)or a Graphic User Interface (GUI) associated with a call. When themobile terminal 100 is in a video call mode or image capturing mode, thedisplay unit 151 may display a captured image and/or received image, aUI or GUI.

The display unit 151 may include at least one of a Liquid CrystalDisplay (LCD), a Thin Film Transistor-LCD (TFT-LCD), an Organic LightEmitting Diode (OLED) display, a flexible display, a three-dimensional(3D) display, and an e-ink display.

Some of those displays may be configured with a transparent or opticaltransparent type to allow viewing of the exterior through the displayunit, which may be called transparent displays. An example of thetypical transparent displays may include a transparent LCD (TOLED), andthe like. Under this configuration, a user can view an object positionedat a rear side of a terminal body through a region occupied by thedisplay unit 151 of the terminal body.

Two or more display units 151 may be implemented according to aconfigured aspect of the mobile terminal 100. For instance, a pluralityof the display units 151 may be arranged on one surface to be spacedapart from or integrated with each other, or may be arranged ondifferent surfaces.

Furthermore, the display unit 151 may be configured with a stereoscopicdisplay unit 152 for displaying a stereoscopic image.

Here, stereoscopic image indicates a 3-dimensional stereoscopic image,and the 3-dimensional stereoscopic image is an image for allowing theuser to feel the gradual depth and reality of an object located on themonitor or screen as in a real space. The 3-dimensional stereoscopicimage may be implemented by using binocular disparity. Here, binoculardisparity denotes a disparity made by the location of two eyes separatedfrom each other, allowing the user to feel the depth and reality of astereoscopic image when two eyes see different two-dimensional imagesand then the images are transferred through the retina and merged in thebrain as a single image.

A stereoscopic method (glasses method), an auto-stereoscopic method(no-glasses method), a projection method (holographic method), and thelike may be applicable to the stereoscopic display unit 152. Thestereoscopic method primarily used in a home television receiver and thelike may include a Wheatstone stereoscopic method and the like.

The examples of the auto-stereoscopic method may include a parallelbarrier method, a lenticular method, an integral imaging method, and thelike. The projection method may include a reflective holographic method,a transmissive holographic method, and the like.

In general, a 3-dimensional stereoscopic image may include a left image(image for the left eye) and a right image (image for the right eye).The method of implementing a 3-dimensional stereoscopic image can bedivided into a top-down method in which a left image and a right imageare disposed at the top and bottom within a frame, a left-to-right(L-to-R) or side by side method in which a left image and a right imageare disposed at the left and right within a frame, a checker boardmethod in which the pieces of a left image and a right image aredisposed in a tile format, an interlaced method in which a left and aright image are alternately disposed for each column and row unit, and atime sequential or frame by frame method in which a left image and aright image are alternately displayed for each time frame, according tothe method of combining a left image and a right image into a3-dimensional stereoscopic image.

For 3-dimensional thumbnail images, a left image thumbnail and a rightimage thumbnail may be generated from the left and the right image ofthe original image frame, and then combined with each other to generatea 3-dimensional stereoscopic image. Typically, thumbnail denotes areduced image or reduced still video. The left and right thumbnail imagegenerated in this manner are displayed with a left and right distancedifference on the screen in a depth corresponding to the disparity ofthe left and right image, thereby implementing a stereoscopic spacefeeling.

A left image and a right image required to implement a 3-dimensionalstereoscopic image are displayed on the stereoscopic display unit 152 bya stereoscopic processing unit (not shown). The stereoscopic processingunit receives a 3D image to extract a left image and a right image fromthe 3D image, or receives a 2D image to convert it into a left image anda right image.

On the other hand, when the display unit 151 and a touch sensitivesensor (hereinafter, referred to as a “touch sensor”) have an interlayerstructure (hereinafter, referred to as a “touch screen”), the displayunit 151 may be used as an input device in addition to an output device.The touch sensor may be implemented as a touch film, a touch sheet, atouch pad, and the like.

The touch sensor may be configured to convert changes of a pressureapplied to a specific part of the display unit 151, or a capacitanceoccurring from a specific part of the display unit 151, into electricinput signals. The touch sensor may be configured to sense not only atouched position and a touched area, but also a touch pressure at whicha touch object body is touched on the touch sensor. Here, the touchobject body may be a finger, a touch pen or stylus pen, a pointer, orthe like as an object by which a touch is applied to the touch sensor.

When there is a touch input to the touch sensor, the correspondingsignals are transmitted to a touch controller. The touch controllerprocesses the signal(s), and then transmits the corresponding data tothe controller 180. Accordingly, the controller 180 may sense whichregion of the display unit 151 has been touched.

Referring to FIG. 1, a proximity sensor 141 may be arranged at an innerregion of the mobile terminal 100 surrounded by the touch screen, oradjacent to the touch screen. The proximity sensor 141 may be providedas an example of the sensing unit 140. The proximity sensor 141 refersto a sensor to sense the presence or absence of an object approaching toa surface to be sensed, or an object disposed adjacent to a surface tobe sensed, by using an electromagnetic field or infrared rays without amechanical contact. The proximity sensor 141 has a longer lifespan and amore enhanced utility than a contact sensor.

The proximity sensor 141 may include an optical transmission typephotoelectric sensor, a direct reflective type photoelectric sensor, amirror reflective type photoelectric sensor, a high-frequencyoscillation proximity sensor, a capacitance type proximity sensor, amagnetic type proximity sensor, an infrared rays proximity sensor, andso on. When the touch screen is implemented as a capacitance type, theproximity of an object having conductivity (hereinafter, referred to asa “pointer”) to the touch screen is sensed by changes of anelectromagnetic field. In this case, the touch screen (touch sensor) maybe categorized into a proximity sensor.

Hereinafter, for the sake of convenience of brief explanation, abehavior that the pointer is positioned to be proximate onto the touchscreen without contact will be referred to as a “proximity touch”,whereas a behavior that the pointer substantially comes in contact withthe touch screen will be referred to as a “contact touch”. For theposition corresponding to the proximity touch of the pointer on thetouch screen, such position corresponds to a position where the pointerfaces perpendicular to the touch screen upon the proximity touch of thepointer.

The proximity sensor 141 senses a proximity touch, and a proximity touchpattern (for example, proximity touch distance, proximity touchdirection, proximity touch speed, proximity touch time, proximity touchposition, proximity touch moving status, etc.). Information relating tothe sensed proximity touch and the sensed proximity touch patterns maybe output onto the touch screen.

When the stereoscopic display unit 152 and a touch sensor are configuredwith an interlayer structure (hereinafter, referred to as a“stereoscopic touch screen”) or the stereoscopic display unit 152 and a3D sensor for detecting a touch operation are combined with each other,the stereoscopic display unit 152 may be used as a 3-dimensional inputdevice.

As an example of the 3D sensor, the sensing unit 140 may include aproximity sensor 141, a stereoscopic touch sensing unit 142, aultrasound sensing unit 143, and a camera sensing unit 144.

The proximity sensor 141 measures a distance between the sensing object(for example, the user's finger or stylus pen) and a detection surfaceto which a touch is applied using an electromagnetic field or infraredrays without a mechanical contact. The terminal may recognize whichportion of a stereoscopic image has been touched by using the measureddistance. In particular, when the touch screen is implemented with acapacitance type, it may be configured such that the proximity level ofa sensing object is sensed by changes of an electromagnetic fieldaccording to the proximity of the sensing object to recognize a3-dimensional touch using the proximity level.

The stereoscopic touch sensing unit 142 may be configured to sense thestrength or duration time of a touch applied to the touch screen. Forexample, stereoscopic touch sensing unit 142 senses a user applied touchpressure, and if the applied pressure is strong, then the stereoscopictouch sensing unit 142 recognizes it as a touch for an object locatedfarther from the touch screen.

The ultrasound sensing unit 143 may be configured to sense the locationof the sensing object using ultrasound.

For example, the ultrasound sensing unit 143 may be configured with anoptical sensor and a plurality of ultrasound sensors. The optical sensormay be formed to sense light, and the ultrasound sensor may be formed tosense ultrasound waves. Since light is far faster than ultrasound waves,the time for light to reach the optical sensor is far faster than thetime for ultrasound waves to reach the ultrasound sensor. Accordingly,the location of the wave generating source may be calculated using atime difference between the light and ultrasound waves to reach theoptical sensor.

The camera sensing unit 144 may include at least one of a camera 121, aphoto sensor, and a laser sensor.

For example, the camera 121 and laser sensor may be combined to eachother to sense a touch of the sensing object to a 3-dimensionalstereoscopic image. Distance information sensed by the laser sensor isadded to a two-dimensional image captured by the camera to acquire3-dimensional information.

For another example, a photo sensor may be deposited on the displayelement. The photo sensor may be configured to scan the motion of thesensing object in proximity to the touch screen. More specifically, thephoto sensor is integrated with photo diodes and transistors in the rowsand columns thereof, and a content placed on the photo sensor may bescanned by using an electrical signal that is changed according to theamount of light applied to the photo diode. In other words, the photosensor performs the coordinate calculation of the sensing objectaccording to the changed amount of light, and the location coordinate ofthe sensing object may be detected through this.

The audio output module 153 may output audio data received from thewireless communication unit 110 or stored in the memory 160, in acall-receiving mode, a call-placing mode, a recording mode, a voicerecognition mode, a broadcast reception mode, and so on. The audiooutput module 153 may output audio signals relating to the functionsperformed in the mobile terminal 100 (e.g., sound alarming a callreceived or a message received, and so on). The audio output module 153may include a receiver, a speaker, a buzzer, and so on.

The alarm 154 outputs signals notifying occurrence of events from themobile terminal 100. The events occurring from the mobile terminal 100may include call received, message received, key signal input, touchinput, and so on. The alarm 154 may output not only video or audiosignals, but also other types of signals such as signals notifyingoccurrence of events in a vibration manner. Since the video or audiosignals can be output through the display unit 151 or the audio outputunit 153, the display unit 151 and the audio output module 153 may becategorized into part of the alarm 154.

The haptic module 155 generates various tactile effects which a user canfeel. A representative example of the tactile effects generated by thehaptic module 154 includes vibration. Vibration generated by the hapticmodule 154 may have a controllable intensity, a controllable pattern,and so on. For instance, different vibration may be output in asynthesized manner or in a sequential manner.

The haptic module 155 may generate various tactile effects, includingnot only vibration, but also arrangement of pins vertically moving withrespect to a skin being touched, air injection force or air suctionforce through an injection hole or a suction hole, touch by a skinsurface, presence or absence of contact with an electrode, effects bystimulus such as an electrostatic force, reproduction of cold or hotfeeling using a heat absorbing device or a heat emitting device, and thelike.

The haptic module 155 may be configured to transmit tactile effectsthrough a user's direct contact, or a user's muscular sense using afinger or a hand. The haptic module 155 may be implemented in two ormore in number according to the configuration of the mobile terminal100.

The memory 160 may store a program for processing and controlling thecontroller 180. Alternatively, the memory 160 may temporarily storeinput/output data (e.g., phonebook, messages, still images, videos, andthe like). Also, the memory 160 may store data related to variouspatterns of vibrations and sounds output upon the touch input on thetouch screen.

The memory 160 may be implemented using any type of suitable storagemedium including a flash memory type, a hard disk type, a multimediacard micro type, a memory card type (e.g., SD or DX memory), RandomAccess Memory (RAM), Static Random Access Memory (SRAM), Read-OnlyMemory (ROM), Electrically Erasable Programmable Read-only Memory(EEPROM), Programmable Read-only Memory (PROM), magnetic memory,magnetic disk, optical disk, and the like. Also, the mobile terminal 100may operate in association with a web storage which performs the storagefunction of the memory 160 on the Internet.

The interface unit 170 may generally be implemented to interface theterminal with external devices connected to the mobile terminal 100. Theinterface unit 170 may allow a data reception from an external device, apower delivery to each component in the mobile terminal 100, or a datatransmission from the mobile terminal 100 to an external device. Theinterface unit 170 may include, for example, wired/wireless headsetports, external charger ports, wired/wireless data ports, memory cardports, ports for coupling devices having an identification module, audioInput/Output (I/O) ports, video I/O ports, earphone ports, and the like.

On the other hand, the identification module may be configured as a chipfor storing various information required to authenticate an authority touse the mobile terminal 100, which may include a User Identity Module(UIM), a Subscriber Identity Module (SIM), and the like. Also, thedevice having the identification module (hereinafter, referred to as“identification device”) may be implemented in a type of smart card.Hence, the identification device can be coupled to the mobile terminal100 via a port.

Furthermore, the interface unit 170 may serve as a path for power to besupplied from an external cradle to the mobile terminal 100 when themobile terminal 100 is connected to the external cradle or as a path fortransferring various command signals inputted from the cradle by a userto the mobile terminal 100. Such various command signals or powerinputted from the cradle may operate as signals for recognizing that themobile terminal 100 has accurately been mounted to the cradle.

The controller 180 typically controls the overall operations of themobile terminal 100. For example, the controller 180 performs thecontrol and processing associated with telephony calls, datacommunications, video calls, and the like. The controller 180 mayinclude a multimedia module 181 which provides multimedia playback. Themultimedia module 181 may be configured as part of the controller 180 oras a separate component.

Furthermore, the controller 180 can perform a pattern recognitionprocessing so as to recognize writing or drawing input carried out onthe touch screen as text or image.

Furthermore, the controller 180 may implement a lock state for limitingthe user's control command input to applications when the state of theterminal satisfies a preset condition. Furthermore, the controller 180may control a lock screen displayed in the lock state based on a touchinput sensed through the display unit 151 in the lock state.

The power supply unit 190 receives external and internal power toprovide power required for various components under the control of thecontroller 180.

Software codes can be implemented by a software application written inany suitable programming language. The software codes may be stored inthe memory 160 and executed by the controller 180.

Next, a communication system that can be implemented through the mobileterminal 100 according to the present disclosure will be described.FIGS. 2A and 2B are conceptual views illustrating a communication systemin which a mobile terminal 100 according to the present disclosure isoperable.

First, referring to FIG. 2A, the communication system may use differentwireless interfaces and/or physical layers. For example, wirelessinterfaces that can be used by the communication system may include,frequency division multiple access (FDMA), time division multiple access(TDMA), code division multiple access (CDMA), universal mobiletelecommunications system (UMTS) (particularly, long term evolution(LTE)), global system for mobile communications (GSM), and the like.

Hereinafter, for the sake of convenience of explanation, the descriptiondisclosed herein will be limited to CDMA. However, it is apparent thatthe present invention may be also applicable to all communicationsystems including a CDMA wireless communication system.

As illustrated in FIG. 2A, a CDMA wireless communication system mayinclude a plurality of terminals 100, a plurality of base stations (BSs)270, a plurality of base station controllers (BSCs) 275, and a mobileswitching center (MSC) 280. The MSC 280 may interface with a PublicSwitched Telephone Network (PSTN) 290, and the MSC 280 may alsointerface with the BSCs 275. The BSCs 275 may be connected to the BSs270 via backhaul lines. The backhaul lines may be configured inaccordance with at least any one of E1/T1, ATM, IP, PPP, Frame Relay,HDSL, ADSL, or xDSL, for example. Further, the system illustrated inFIG. 2A may include a plurality of BSCs 275.

Each of the plurality of BSs 270 may include at least one sector, eachsector having an omni-directional antenna or an antenna indicating aparticular radial direction from the base station 270. Alternatively,each sector may include two or more antennas with various forms. Each ofthe BSs 270 may be configured to support a plurality of frequencyassignments, each frequency assignment having a particular spectrum (forexample, 1.25 MHz, 5 MHz, etc.).

The intersection of a sector and frequency assignment may be referred toas a CDMA channel. The BSs 270 may also be referred to as Base StationTransceiver Subsystems (BTSs). In this case, the term “base station” maycollectively refer to a BSC 275, and at least one BS 270. The basestations may also indicate “cell sites”. Alternatively, individualsectors for a specific BS 270 may also be referred to as a plurality ofcell sites.

As illustrated in FIG. 2A, the Broadcasting Transmitter (BT) 295 maytransmit broadcasting signals to the terminals 100 being operated withinthe system. The broadcast receiving module 111 as illustrated in FIG. 1may be provided in the mobile terminal 100 to receive broadcast signalstransmitted by the BT 295.

In addition, FIG. 2A illustrates several global positioning system (GPS)satellites 300. Such satellites 300 facilitate locating at least one ofa plurality of terminals 100. Though two satellites are illustrated inFIG. 2A, location information may be obtained with a greater or fewernumber of satellites. The location information module 115 as illustratedin FIG. 1 may cooperate with the satellites 300 as illustrated in FIG.2A to obtain desired location information. However, other types ofposition detection technology, all types of technologies capable oftracing the location may be used in addition to a GPS locationtechnology. Furthermore, at least one of the GPS satellites 300 mayalternatively or additionally provide satellite DMB transmissions.

During the operation of a wireless communication system, the BS 270 mayreceive reverse-link signals from various terminals 100. At this time,he terminals 100 may perform calls, message transmissions andreceptions, and other communication operations. Each reverse-link signalreceived by a specific base station 270 may be processed within thatspecific base station 270. The processed resultant data may betransmitted to an associated BSC 275. The BSC 275 may provide callresource allocation and mobility management functions including thesystemization of soft handoffs between the base stations 270.Furthermore, the BSCs 275 may also transmit the received data to the MSC280, which provides additional transmission services for interfacingwith the PSTN 290. Furthermore, similarly, the PSTN 290 may interfacewith the MSC 280, and the MSC 280 may interface with the BSCs 275. TheBSCs 275 may also control the BSs 270 to transmit forward-link signalsto the terminals 100.

Next, a method of acquiring the location information of a terminal usinga WiFi (Wireless Fidelity) positioning system (WPS) will be describedwith reference to FIG. 2B.

The WiFi positioning system (WPS) 300 refers to a location determinationtechnology based on a wireless local area network (WLAN) using WiFi as atechnology for tracking the location of the mobile terminal 100 using aWiFi module provided in the mobile terminal 100 and a wireless accesspoint 320 for transmitting and receiving to and from the WiFi module.

The WiFi positioning system 300 may include a WiFi locationdetermination server 310, a mobile terminal 100, a wireless access point(AP) 320 connected to the mobile terminal 100, and a database 330 storedwith any wireless AP information.

The WiFi location determination server 310 extracts the information ofthe wireless AP 320 connected to the mobile terminal 100 based on alocation information request message (or signal) of the mobile terminal100. The information of the wireless AP 320 may be transmitted to theWiFi location determination server 310 through the mobile terminal 100or transmitted to the WiFi location determination server 310 from thewireless AP 320.

The information of the wireless AP extracted based on the locationinformation request message of the mobile terminal 100 may be at leastone of MAC address, SSID, RSSI, channel information, privacy, networktype, signal strength and noise strength.

The WiFi location determination server 310 receives the information ofthe wireless AP 320 connected to the mobile terminal 100 as describedabove, and compares the received wireless AP 320 information withinformation contained in the pre-established database 330 to extract (oranalyze) the location information of the mobile terminal 100.

On the other hand, referring to FIG. 2B, as an example, the wireless APconnected to the mobile terminal 100 is illustrated as a first, asecond, and a third wireless AP 320. However, the number of wireless APsconnected to the mobile terminal 100 may be changed in various waysaccording to a wireless communication environment in which the mobileterminal 100 is located. When the mobile terminal 100 is connected to atleast one of wireless APs, the WiFi positioning system 300 can track thelocation of the mobile terminal 100.

Next, considering the database 330 stored with any wireless APinformation in more detail, various information of any wireless APsdisposed at different locations may be stored in the database 330.

The information of any wireless APs stored in the database 330 may beinformation such as MAC address, SSID, RSSI, channel information,privacy, network type, latitude and longitude coordinate, building atwhich the wireless AP is located, floor number, detailed indoor locationinformation (GPS coordinate available), AP owner's address, phonenumber, and the like.

In this manner, any wireless AP information and location informationcorresponding to the any wireless AP are stored together in the database330, and thus the WiFi location determination server 310 may retrievewireless AP information corresponding to the information of the wirelessAP 320 connected to the mobile terminal 100 from the database 330 toextract the location information matched to the searched wireless AP,thereby extracting the location information of the mobile terminal 100.

FIG. 3A is a front perspective view illustrating an example of themobile terminal 100 associated with the present disclosure.

The touch sensing means may be formed with transparency to allow visualinformation displayed on the display unit 151 to be seen, and mayinclude a structure for enhancing the visibility of a touch screen atbright places. Referring to FIG. 3A, the display unit 151 occupies amost portion of the front surface of the front case 101.

The first audio output unit 153 a and the first camera 121 a aredisposed in a region adjacent to one of both ends of the display unit151, and the first manipulation input unit 131 and the microphone 122are disposed in a region adjacent to the other end thereof. The secondmanipulation interface 132 (refer to FIG. 3B), the interface 170, andthe like may be disposed on a lateral surface of the terminal body.

The first audio output module 153 a may be implemented in the form of areceiver for transferring voice sounds to the user's ear or a loudspeaker for outputting various alarm sounds or multimedia reproductionsounds.

It may be configured such that the sounds generated from the first audiooutput module 153 a are released along an assembly gap between thestructural bodies. In this case, a hole independently formed to outputaudio sounds may not be seen or hidden in terms of appearance, therebyfurther simplifying the appearance of the mobile terminal 100. However,the present invention may not be limited to this, but a hole forreleasing the sounds may be formed on the window.

The first camera 121 a processes video frames such as still or movingimages obtained by the image sensor in a video call mode or capturemode. The processed video frames may be displayed on the display unit151.

The user input unit 130 is manipulated to receive a command forcontrolling the operation of the mobile terminal 100. The user inputunit 130 may include a first and a second manipulation unit 131, 132.The first and the second manipulation unit 131, 132 may be commonlyreferred to as a manipulating portion, and any method may be employed ifit is a tactile manner allowing the user to perform manipulation with atactile feeling such as touch, push, scroll or the like.

In the present drawing, it is illustrated on the basis that the firstmanipulation unit 131 is a touch key, but the present disclosure may notbe necessarily limited to this. For example, the first manipulation unit131 may be configured with a mechanical key, or a combination of a touchkey and a mechanical key.

The content received by the first and/or second manipulation units 131,132 may be set in various ways. For example, the first manipulation unit131 may be used to receive a command such as menu, home key, cancel,search, or the like, and the second manipulation unit 132 may receive acommand, such as controlling a volume level being output from the firstaudio output module 153 a, or switching into a touch recognition mode ofthe display unit 151.

The microphone 122 may be formed to receive the user's voice, othersounds, or the like. The microphone 122 may be provided at a pluralityof places, and configured to receive stereo sounds.

The interface unit 170 serves as a path allowing the mobile terminal 100to exchange data with external devices. For example, the interface unit170 may be at least one of a connection terminal for connecting to anearphone in a wired or wireless manner, a port for near fieldcommunication (for example, an Infrared Data Association (IrDA) port, aBluetooth port, a wireless LAN port, and the like), and a power supplyterminal for supplying power to the mobile terminal 100. The interfaceunit 170 may be implemented in the form of a socket for accommodating anexternal card such as Subscriber Identification Module (SIM) or UserIdentity Module (UIM), and a memory card for information storage.

FIG. 3B is a rear perspective view illustrating mobile terminal 100illustrated in FIG. 3A.

Referring to FIG. 3B, a second camera 121 b may be additionally mountedat a rear surface of the terminal body, namely, the rear case 102. Thesecond camera 121 b has an image capturing direction, which issubstantially opposite to the direction of the first camera unit 121 a(refer to FIG. 3A), and may have a different number of pixels from thatof the first camera unit 121 a.

For example, it is preferable that the first camera 121 a has arelatively small number of pixels enough not to cause difficulty whenthe user captures his or her own face and sends it to the other partyduring a video call or the like, and the second camera 121 b has arelatively large number of pixels since the user often captures ageneral object that is not sent immediately. The first and the secondcamera 121 a, 121 b may be provided in the terminal body in a rotatableand popupable manner.

Furthermore, a flash 123 and a mirror 124 may be additionally disposedadjacent to the second camera 121 b. The flash 123 illuminates lighttoward an object when capturing the object with the second camera 121 b.The mirror 124 allows the user to look at his or her own face, or thelike, in a reflected way when capturing himself or herself (in aself-portrait mode) by using the second camera 121 b.

A second audio output unit 153 b may be additionally disposed at a rearsurface of the terminal body. The second audio output unit 153 btogether with the first audio output unit 153 a (refer to FIG. 3A) canimplement a stereo function, and may be also used to implement a speakerphone mode during a phone call.

An antenna (not shown) for receiving broadcast signals may beadditionally disposed at a lateral surface of the terminal body inaddition to an antenna for making a phone call or the like. The antennaconstituting part of the broadcast receiving module 111 (refer toFIG. 1) may be provided in the terminal body in a retractable manner.

A power supply unit 190 (refer to FIG. 1) for supplying power to themobile terminal 100 may be mounted on the terminal body. The powersupply unit 190 may be incorporated into the terminal body, or mayinclude a battery 191 configured in a detachable manner on the outsideof the terminal body. According to the drawing, it is illustrated thatthe battery cover 103 is combined with the rear case 102 to cover thebattery 191, thereby restricting the battery 191 from being released andprotecting the battery 191 from external shocks and foreign substances.

Furthermore, the extracted location information of the mobile terminal100 may be transmitted to the mobile terminal 100 through the WiFilocation determination server 310, thereby allowing the mobile terminal100 to acquire location information.

FIG. 4 is a cross-sectional view for explaining the internalconfiguration of a camera module constituting a camera 121 according toan embodiment of the present disclosure. The camera module according toan embodiment may include a plurality of lenses 121 c, a light fieldengine 121 d and a light field sensor 121 e.

The light field sensor 121 e may be formed such that the sensor sensesand record light moving in all directions over substantially entireregions (a space in which light is illuminated). The light field sensor121 e acquires images for which the focuses are formed on differentranges, namely, depths, according to the size of an iris contained inthe camera terminal. A camera module according to the present embodimentis formed to collect image information at different angles,respectively, at a time to store them in the memory 160, instead offocusing on objects to be captured.

A camera module according to an embodiment records the directioninformation of light reflected from an object, whether it is reflectedlight from how far from the camera module or incident light in whichdirection. Though not shown in the drawing, the images may be convertedand displayed into 2-dimensional or 3-dimensinal images. Accordingly,the focus can be changed from the acquired one image.

In other words, the display unit 151 of the mobile terminal according tothe present disclosure displays an image acquired by the camera 121. Thecontroller controls the display unit 151 to display a representativeimage among a plurality of different images stored in the memory.Furthermore, the controller controls the display unit 151 to convert therepresentative image to another image based on a touch input applied tothe display unit 151.

According to an embodiment of the present disclosure, the controllercontrols the display unit 151 to display one representative image ordisplay a plurality of representative images stored in the memory atonce. When at least one representative image is displayed on the displayunit 151, the controller controls the display unit 151 to displayanother image associated with the plurality of representative images,respectively, based on the user's touch input applied to the displayunit 151.

Here, another image associated with the representative image, as animage acquired at a substantially same time as the representative imagebased on the user's capture control command, corresponds to an image forwhich the focus is formed on a different configuration (or differentregion) or image for which an object contained in the representativeimage is acquired at a different angle from the representative image.

Hereinafter, a control method of changing an image based on a touchinput applied to the display unit 151 will be described.

FIG. 5 is a flow chart for explaining a control method of a mobileterminal according to an embodiment of the present disclosure, and FIG.6A is a conceptual view for explaining the control method of FIG. 5according to each embodiment.

The camera 121 acquires a plurality of images having different focusesat a substantially same time based on the user's control command (S501).For example, when a camera application for acquiring an externalenvironment as an image is activated to display a preview image of theexternal environment on the display unit 151, a plurality of images areacquired based on a capture icon displayed on the display unit 151 or acontrol command applied to the signal input unit formed on the body ofthe mobile terminal.

Referring to FIG. 6A, a plurality of images are acquired at differentangles at a substantially same time, and the focuses thereof are formedat different locations. The plurality of images for which the focusesare formed at different locations are acquired based on the same controlcommand applied by the user. For example, when the camera applicationand the camera are activated to acquire images, a plurality of imagesare acquired at a substantially same time based on one control commandapplied to the mobile terminal. The plurality of images are stored inthe memory 160 (S502), and the controller 180 controls the display unit151 to display one of the plurality of stored images as a representativeimage 510 (S503).

For example, 6A corresponds to an execution screen in which one image ofthe execution screen of a gallery application for displaying photosstored therein is selected and displayed. However, it may not benecessarily limited to this, and correspond to the execution screen ofan application for editing photos, screen information in case ofuploading photos online, or the like.

For the sake of convenience of explanation, a region in which the focusis clearly adjusted is illustrated as a bold line, a region in which thefocus is not adjusted and shown in a blurred manner as a dotted line,and a region with an intermediate level of focus as a solid line. Anobject corresponding to the region displayed with a dotted line may bedimly seen in actuality and thus formed in such a manner that the shapeis blurred or the edge of the object is not clear.

In other words, the controller 180 controls the camera to image theexternal environment such that the focus is formed on one region and theone region is clearly shown but the remaining region is shown in arelatively dim manner. The plurality of images are formed such that thefocused and relatively clearly imaged regions compared to the otherregion are differently shown. Accordingly, the plurality of images maybe formed such that their focuses are adjusted on substantiallydifferent objects and clearly shown objects are differently shown.

The controller 180 controls the display unit 151 to display an imageselected in an arbitrary manner or preset criteria from the plurality ofimages as a representative image. Here, the preset criteria may bedetermined based on a preset angle or focal length based on the internalstructure of a cameral module, and the criteria may be applicable invarious ways. Hereinafter, a control method of converting therepresentative image 510 to another associated image will be described.

Referring to FIG. 6A, the controller 180 controls the display unit 151to display a representative image 510 among a plurality of images storedin the memory 160. The controller 180 displays an icon that receives atouch input to display another image associated with the representativeimage 510 for which the focus is formed on a different location (orobject) based on a control command applied in a state that therepresentative image 510 is displayed.

The icon may include a list for deleting the representative image 510,moving it to another photo folder, or editing the representative image.

Referring to FIG. 6A, when a touch input is applied to an icon (focuschange) to convert the representative image 510 to the another image,the controller 180 controls the display unit 151 to display a firstcontrol image 510 for selecting another image having the differentfocus.

The first control image 510 is formed with a continuous (vertical)scroll bar. A scroll box contained in the scroll bar corresponds to aplurality of focuses applied to the plurality of images. In other words,the controller 180 may control the display unit 151 to move the scrollbox so as to display another image containing the different focus. Inother words, the scroll bar extended in one direction is divided tocorrespond to the number of images, and when the scroll box is locatedat one region of each scroll bar by the user, the controller 180controls the display unit 151 to display an image corresponding to theone region.

Furthermore, the controller 180 may control the display unit 151 toconsecutively convert the plurality of different images based on adragging type touch input for consecutively moving the scroll box of thefirst control image 610. Accordingly, it may be seen to the user suchthat only the focus of an image containing the same object isconsecutively changed. In other words, it may be displayed in such amanner that a clearly expressed region on the substantially same imageis varied.

For example, when three persons are included in an external environment,the controller 180 controls the memory 160 to acquire three images forwhich the focuses are formed on the three persons, respectively, at thesame time by the camera, and store the three images. The scroll bar aredivided into three regions, and when the scroll box is located in one ofthe three regions, the controller 180 controls the display unit 151 todisplay an image for which the focus is formed on a person correspondingto the one region.

Referring to FIG. 6A, the controller 180 controls the display unit 151to display another image for which the focus is formed on a differentregion from that of which the focus is formed on the representativeimage 610 and acquired by a substantially same control command as thatof the representative image 610 based on a touch input applied to thefirst input window 610. In other words, the representative image isconverted to another image (S504).

The controller 180 can store another image 511 for which the focus hasbeen changed based on a touch input applied to an icon for storing animage displayed on the display unit 151. The storage of the anotherimage 511 denotes storing a representative image displayed on thedisplay unit 151 as the another image 511. Accordingly, the user cancontrol the display unit to display an image for which the focus isformed on his or her desired object or one region. For example, thecontroller 180 may control the display unit 151 to immediately displayan image to which the changed focus is applied based on a controlcommand for activating a gallery application that displays imagesacquired by the camera 121.

However, the present disclosure may not be necessarily limited to this,and the controller 180 may control the memory to store the another image511 in addition to the representative image 510. Accordingly, the sameobject may be acquired at a substantially same time in the storage spaceof the gallery application, and the representative image 510 and theanother image 511 for which the focuses are formed on different regionsmay be stored at once.

According to the present embodiment, the user may apply a touch input tothe display unit 151 that displays the acquired photos to receive imagesfor which the focus has been changed on the photo or store them in aseparate manner. Furthermore, though not shown in the drawing, anadditional function, such as sharing an image for which the focus hasbeen changed using another application or the like, may be carried outbased on a touch input applied to the display unit 151.

A control method of changing the focus of an image and editing oneregion of the image will be described with reference to FIG. 6B.

Referring to FIG. 6B, when the representative image 510 is displayed onthe display unit 151, the controller 180 controls the display unit 151to display a first control image 610 based on a touch input applied tothe display unit 151.

The first control image 610 is formed with a scroll bar shape containinga scroll box. Furthermore, the first control image 610 may include aplurality of thumbnail views 611 and at least one first edit icon 612.

The plurality of thumbnail views 611 are formed to correspond to thenumber of a plurality of images acquired by the camera 121, and formedto display a region corresponding to the focus of each image. In otherwords, the thumbnail views 611 display different one region of theimage.

The thumbnail views 611 are displayed adjacent to the scroll bar, anddisposed to be separated from one another. However, it may be allowed tohave irregular distances between each thumbnail view 611. For example,when a plurality of focal lengths applied to the camera 121 are notspecified in a regular manner, a distance between thumbnail views 611corresponding to each focus may be formed in an irregular manner.

The controller 180 may change the representative image 510 to anotherimage 511 based on a touch input applied to the first control image 610to move the scroll box to be adjacent to each thumbnail view 611. Thecontroller 180 controls the display unit 151 to display another image511 for which the focus is formed on an object shown on the thumbnailview 611 displayed in a region adjacent to the scroll box.

The another image 511 may be configured in such a manner that the focusformed on the representative image 511 is formed on a different region,and accordingly, a clearly displayed region on the representative image511 may be different from that of the another image 511. In other words,the controller 180 may display another image 511 for which a regioncorresponding to the thumbnail view 611 is clearly shown.

The controller 180 controls the display unit 151 to cut only part of theanother image 511 based on a touch input applied to the first edit icon612. In other words, the controller 180 controls the display unit 151 totake and display only the selected one edit region 512 based on a touchinput applied to the icon of the another image 511.

A first edit icon 612 may be formed between the each thumbnail view 611.For example, referring to FIG. 6B, the controller 180 controls thedisplay unit 151 to display an edit region 512 contained in thethumbnail view 611 at the top based on a touch input applied to thefirst edit icon 612 formed between the two thumbnail views 611.

For example, when a touch input is applied to two first edit icons 612in FIG. 6B, the controller 180 may control the display unit 151 todisplay an edit region displayed in the middle of the three thumbnailviews 611.

A touch input for displaying the edit region 512 is unrelated to a touchinput applied to the scroll box for adjusting the focus of the image. Inother words, the edit image may be displayed in a blurred state forwhich the focus is not adjusted based on a touch input applied to thefirst edit icon 612.

Furthermore, the controller 180 may store the edit region 512 in aseparate manner based on a touch input applied to the display unit 151in a state that the edit region 512 is displayed.

Accordingly, the user can change a focused region as well as edit anddisplay one separated region based on the focused region.

A control method of adjusting the definition of a focused region will bedescribed with reference to FIG. 6C. Referring to FIG. 6C, thecontroller 180 controls the display unit 151 to display a second editicon 613 on the second control image 620. The second edit icon 613 maybe formed with a scroll bar shape extended in the horizontal direction,and a plurality of second edit icons 613 may be formed in a regionadjacent to the thumbnail view 611.

The controller 180 may control the display unit 151 to adjust thedefinition of each region of the image displayed on the thumbnail view611 based on a touch input applied to the second edit icon 613.

For the second control image 620, a touch input may be applied in thehorizontal direction to increase or decrease the definition of a regioncorresponding to the thumbnail view 611. However, the definition of anunfocused region may be restricted not to be increased greater than thatof a focused region. In other words, the controller 180 controls thedisplay unit 151 to display another image 511′ having an adjusteddefinition.

Accordingly, the user can adjust the definition of a divided region.

FIGS. 7A through 7D are conceptual views for explaining various controlmethods of tracking a figure when a plurality of figures are containedin an image.

A control method of forming a focus around a figure contained in theimage will be described with reference to FIG. 7A. FIG. 7A is a viewillustrating the display unit 151 on which a representative image 520containing a plurality of figures is displayed. For example, itcorresponds to an image in which three figures are located at differentlocations, and the focus is adjusted on one figure. A figure for whichthe focus is well adjusted is illustrated as a bold line, a figure forwhich the focus is not adjusted and shown in a blurred manner as adotted line, and a figure for which an intermediate level of focus isadjusted as a solid line.

The controller 180 tracks a figure contained in the representative image520 based on the touch input. Furthermore, the controller 180 controlsthe display unit 151 to display the second control image 620 based onthe tracked figure.

The second control image 620 may be displayed at a lateral surface ofthe representative image 520 or at least part of that may be formed tobe overlapped with the representative image 520. The second controlimage 620 may include a graphic image 621 containing an image of thetracked figure. Furthermore, the controller 180 controls the displayunit 151 to display a representative name corresponding to the trackedfigure along with the graphic image 621.

The controller 180 may analyze the tracked figure to perform a functionof retrieving whether or not there is information matched to data storedin the memory 160 or retrieving whether or not there is informationmatched to an image of the figure on the web. When there is the matchedinformation, the controller 180 controls the display unit 151 to applythe matched information to the graphic image and display it. However,when the matched information is not found, the controller 180 may notrecord a representative name and the like or control the display unit151 to display notification information indicating that it has not beenfound.

An image contained in the graphic image 621 may correspond to arepresentative image (for example, an image stored in the address book)of the information of the tracked figure or correspond to a figure imageof the representative image 520.

The representative images 520 are formed to receive a touch input, anddisplayed to be separated from one another on the second control image620. Furthermore, the controller 180 controls the display unit 151 toarrange and display them in the definition order of graphic images 621corresponding to the each figure.

For example, the controller 180 controls the display unit 151 to displaysuch that a graphic image 621 corresponding to a figure for which thefocus is most correctly adjusted on the figure's face is disposed at thetop, and a graphic image 621 corresponding to a figure for which thefocus is not correctly adjusted on the figure's face is disposed at thebottom.

Accordingly, the user can confirm whose figure is contained in therepresentative image and receive the information of a figure for whichthe focus is not adjusted and shown in a blurred manner. Furthermore,the user can receive information on the focus on the representativeimage 520.

Referring to FIG. 7A, the controller 180 may control the display unit151 to change and display the location of graphic images 621 arranged soas to provide the focus information of a figure based on the user'stouch input (for example, a dragging type touch input).

The controller 180 may move the location of the graphic image (B) toanother region based on a consecutive touch input applied to the onegraphic image (B). Accordingly, the sequence of the graphic images maybe A-C-B.

The controller 180 controls the display unit 151 to change the focus ofthe representative image 520 based on the sequence of the graphic images621. In other words, the controller 180 controls the display unit 151 todisplay another image 521 for which the focus is formed on a regiondifferent from that of the representative image 520 by a graphic image621 contained in the second control image 620 in which the arrangementis changed. Accordingly, the user can recognize that the focus of animage is changed based on a touch input applied to the second controlimage 620.

The controller 180 may control the display unit 151 to change a focusadjusted on the figure by the graphic image 621 in which the arrangementis changed. In other words, the controller 180 controls the display unit151 not to adjust the focus on a figure contained in the one graphicimage (B) (namely, focus-out), and display another image 521 for whichan intermediate level of focus is adjusted on a figure contained in onegraphic image (C) moved to a relatively medium region.

In other words, the user may move the location of the graphic image 621containing the information of a figure to check the figure on the imageor receive an image in which the selected figure is clearly shown.

A control method of applying a touch input to an image to change afigure on the image for which the focus is adjusted will be describedwith reference to FIG. 7B. Referring to FIG. 7B, the controller 180controls the display unit 151 to display an icon that receives a controlcommand for changing a focus based on a touch input applied to thedisplay unit 151.

The controller 180 controls the display unit 151 to display a thirdcontrol image 630 displayed on the representative image 520 based on atouch input applied to the icon. The third control image 630 is formedwith a plurality of graphic images displayed for figures, respectively,contained in the representative image 520.

Furthermore, the third control image 630 may include a numeralcorresponding to the order for which each focus is adjusted and clearlyshown.

First, the controller 180 tracks a figure contained in therepresentative image 520 based on a touch input applied to the icon. Thecontroller 180 display a graphic image to allow the user to recognize aregion of the tracked figure. For example, the controller 180 controlsthe display unit 151 to display the graphic image with an indicatorsurrounding the face of the tracked figure.

The third control image 630 configured with the plurality of graphicimages is formed to receive a touch input. Referring to FIG. 7B, thecontroller 180 controls the display unit 151 such that the focus isformed on a figure corresponding to the graphic image to which a touchinput is applied based on the touch input applied to one graphic imageof the third control image 630. In other words, the controller 180controls the display unit 151 to convert the representative image 520 toanother image 522 for which the focus is formed on the correspondingfigure.

Referring to FIG. 7B, the controller 180 may control the display unit151 to change the focus of the relevant figure based on a touch inputapplied to the another graphic image. In other words, the controller 180may change the focus of a figure corresponding to another graphic imagebased on a touch input applied to the another graphic image. However,the controller 180 may form in such a manner that the focus is moreblurred than that of the figure of a graphic image to which a touchinput is first applied.

In other words, the controller 180 controls the display unit 151 toadjust the focus on a figure to which a first touch input is applied,and display a changed image 623 for which the focus is less clearlyadjusted than that of a figure to which a second touch input applied.

However, a control method of changing the image or changing a focusregion may not be necessarily limited to this. For example, when twofigures are displayed on the image, the controller 180 may control thedisplay unit 151 such that the focus is formed on the figure of agraphic image to which the touch input is applied, and the focus is notformed (focus-out) on another figure.

Furthermore, the controller 180 may control the display unit 151 tosequentially change images for which the focus is formed on the figureto images for which the focus is not formed (focus-out) based on a touchinput repetitively applied to the graphic image.

Accordingly, the user can receive a figure contained in a graphic imageand selectively form a focus on the figure.

A control method of performing an additional function using the trackedfigure will be described with reference to FIG. 7C.

The controller 180 controls the display unit 151 to track a figurecontained in the representative image 520 based on a touch input appliedto the display unit 151, and display a second control image 620.However, as illustrated in the drawing, the controller 180 may controlthe display unit 151 to display an indicator (a graphic image of thethird control image 630, refer to FIG. 7B) in one region of the figureto display the location of the figure contained in the representativeimage 520.

The controller 180 controls the display unit 151 to display a pluralityof icons 623 for executing a function for a figure corresponding to thetouched graphic image 621 based on a touch input applied to the graphicimage 621 of the second control image 620.

For example, the icon 623 may include an execution icon of a phoneapplication for sending a call to an external terminal matched to thefigure, an execution icon of a message application for sending a textmessage to the external terminal, an execution icon of an address bookapplication for outputting information on the figure, and the like.

However, it may not be necessarily limited to this, and the icon 623 mayinclude an execution icon of an application that is unrelated to theselected figure. For example, the icon 623 may include a memoapplication, a GPS execution icon for recognizing a current location,and the like. The controller 180 may execute a function for tagginginformation to the selected figure by the execution of the memoapplication.

Furthermore, the controller 180 may control the display unit 151 toadjust the brightness of one region of the each figure based on a touchinput applied to the graphic image 621. For example, the controller 180may control the display unit 151 to display a figure selected by thegraphic image 621 in a bright manner, and the rest figures in a dimmanner.

According to the present embodiment, the user can more easily executeanother application program (or another function) associated with thetracked figure on a representative image.

A control method of receiving additional information associated with thetracked figure and the figures will be described with reference to FIG.7D. Referring to FIG. 7D, the controller 180 tracks a figure containedin the representative image 520. The controller 180 may control thedisplay unit 151 to display information matched to the tracked figure.

For example, the controller 180 may control the display unit 151 todisplay the information (for example, information stored in the storagespace of an address book application) of an external terminal matched tothe figure. Furthermore, the controller 180 may control the display unit151 to display the other information of a substantially same categoryother than information matched to the figure. In other words, thecontroller 180 may control the display unit 151 to display the otherinformation of the external terminal stored in the storage space of theaddress book application at the same time.

However, the present disclosure may not be necessarily limited to this,and the controller 180 may control the display unit 151 to displayinformation on various figures associated with the tracked information.Here, the figure associated with the information may correspond to afigure (for example, a figure contained in or associated with thefriendship or the same group) associated through a social network.

Accordingly, the user can more easily receive information regarding afigure contained in the representative image or information associatedwith the figure.

Furthermore, information regarding the tracked figure is formed with afourth control image 640 for receiving a touch input. The controller 180may control the display unit 151 to convert the representative image 520to another image 521 for which the focus is changed based on a touchinput applied to the fourth control image 640.

Referring to FIG. 7D, the controller 180 may share an image based on atouch input applied to the fourth control image 640. For example, thecontroller 180 may control the image to be transmitted to the externalterminal of the selected figure.

For example, when a figure selected by the touch input is not containedin the representative image 520, the controller may transmit therepresentative image 520 to the external terminal of the figure.

Hereinafter, when a figure selected by the user is contained in therepresentative image, a control method of sharing it will be describedwith reference to 7E.

Referring to FIG. 7E, when a figure contained in the representativeimage 520 is selected by the user's touch, the organicelectroluminescent device 10 controls the display unit to displayanother image 521 for which the focus is adjusted on the figure toclearly exhibit the figure.

When a share method is selected by the user's touch input, thecontroller 180 controls the another image 521 to be shared for theselected figure. On the other hand, when a figure contained in therepresentative image 520 is selected for a share object without theprocess of selecting the share method, the controller may control theanother image 521 to be shared.

For example, when a figure (JOHN) contained in the representative image520 is selected for an object to be shared, the controller activates amessage application to form the send number as the phone number of thefigure (JOHN). Furthermore, the controller 180 controls the display unit151 to display an execution screen of the application in a state thatanother image for which the focus is formed on the figure (JOHN) andclearly shown is automatically appended.

Accordingly, the user can selectively share an image for which a figurefor sharing the image is clearly shown without an additional controlcommand for adjusting the definition.

However, the present disclosure may not be necessarily limited to this,and when uploading an image such as SNS, in case where a figurecontained in the representative image is tagged while the user uploadsthe representative image, the controller may control another image forwhich the tagged figure is clearly shown to be uploaded. In other words,when the representative image 520 is used as information correspondingto a figure contained in the representative image 520, the controllermay control such that it is converted to another image for which thefocus is clearly formed on the figure to perform a function.

FIGS. 8A through 8C are conceptual views for explaining a control methodof changing focuses when a plurality of representative images aredisplayed at once.

A control method of selecting the tracked figure to change the focuswill be described with reference to FIG. 8A. FIG. 8A illustrates screeninformation 530 in which a plurality of representative images aredisplayed at once. For example, the screen information 530 is one of theexecution screens of a gallery application for displaying the acquiredphotos. In other words, it corresponds to screen information in which aplurality of photos stored in the storage space of the galleryapplication are displayed at a time, and the user can apply a touchinput to one of the photos to display a photo in an enlarged manner.

Representative images contained in the screen information 530 are photosacquired by the camera 121, and the memory 160 stores the representativeimages and their associated images captured at a plurality of focusesand angles. However, the present disclosure may not be necessarilylimited to this, and if it is a representative image containingassociated images acquired at a substantially same time and acquired atvarious angles with various focuses, then it may be also allowed whendownloaded or separately stored.

The controller 180 tracks a figure contained in the plurality ofrepresentative images based on a preset control command applied whiledisplaying the screen information 530. The controller 180 controls thedisplay unit 151 to display a fifth control image 650 containing thetracked figure and information (for example, the representative name ofthe figure stored in the memory 160) corresponding to the figure. Thefifth control image 650 may include a plurality of graphic imagescontaining the information of the each figure.

For example, the controller 180 may include a first representative image530 a containing a first and a second figure, a second representativeimage 530 b containing a third figure, and a third representative image530 c containing a second figure.

The controller 180 controls the display unit 151 to form an indicator onthe first figure in the each representative image based on a touch inputapplied to a graphic image corresponding to the first figure (MOM)contained in the fifth control image 650.

Furthermore, the controller 180 controls the display unit 151 to changethe focus of at least one representative image containing the firstfigure. For example, the controller controls the display unit 151 tochange it to another image 530 a′ for which the focus is formed on thefirst figure among associated images acquired at a substantially sametime along with the first representative image 530′.

Furthermore, the controller 180 controls the display unit 151 to displaya representative image that does not contain the first figure (MOM) in adark manner. For example, the controller 180 controls the display unit151 to display the second and the third representative image 530 b, 530c in a dark manner based on a touch input applied to a graphic imagecorresponding to the first figure (MOM).

Referring to FIG. 8A, the controller 180 controls the display unit 151to form a focus to the second figure on a graphic image containing thesecond figure based on a touch input applied to a graphic imagecorresponding to the second figure (FRIEND).

For example, the controller 180 controls the display unit 151 to displaya representative image (for example, the third representative image)containing the second figure in a bright manner.

Referring to a third representative image 530 c containing only thesecond figure, the controller 180 controls the display unit 151 todisplay another image 530 c′ associated with the third representativeimage 530 for which the focus is formed on the second figure.

Referring to a second representative image 530 b containing the firstand the second figure, the controller 180 controls the display unit 151to display another image 530 b′ associated with the secondrepresentative image 530 b for which the focus is formed on the firstand the second figure. The another image 530 b′ may correspond to animage for which the focus is more accurately formed on either one of thefirst and the second figure.

For example, the controller 180 may determine a level at which the focusis adjusted according to the sequence of touch inputs applied to thefifth control image 650.

According to the present embodiment, when a plurality of representativeimages are displayed at once on the display unit 151, the user cancontrol such that representative images containing the figure areautomatically selected to adjust a focus on the figure at the same timebased on one touch input for selecting the figure.

Though not specifically shown in the drawing, the user can concurrentlystore images formed at the same time by the fifth control image 650.

A control method of changing the focus level of a plurality of figuresselected from the fifth control image will be described with referenceto FIG. 8B. FIG. 8B illustrates the display unit 151 on which aplurality of images for which the focus is formed on the first and thesecond figure are displayed based on a touch input applied to thegraphic images of the first and the second figure contained in the fifthcontrol image 650.

The controller 180 may display the graphic image with a different shapeto indicate that the graphic image has been selected based on a touchinput applied to the graphic images of the each figure. For example, thedisplay unit 151 may modify and display the brightness and color of thegraphic image or process and display the graphic image in a highlightedmanner. Accordingly, the user can recognize the selected figure.

The controller 180 may control the display unit 151 to change thelocation of a graphic image corresponding to each figure on the fifthcontrol image 650 by a touch input (for example, a consecutive input, adragging type touch input, etc.) applied to the graphic image in a statethat the focus is formed on the plurality of figures.

For example, the controller 180 may control the display unit 151 tosubstitute the location of the graphic image of the second figure withthe location of the graphic image of the first figure based on aconsecutive touch input applied to the graphic image corresponding tothe second figure.

However, the present disclosure may not be necessarily limited to theillustration of FIG. 8B, and the controller 180 may control the displayunit 151 to display the graphic image of the first and the second figurerather than a graphic image (MAN) corresponding to the non-selectedfigure thereon.

When the location of the graphic image of the first and the secondfigure is changed based on the touch input, the controller 180 controlsthe display unit 151 to more accurately adjust the focus of the secondfigure than that of the second figure.

For example, referring to a first representative image 530 a, thecontroller 180 controls the display unit 151 to convert the firstrepresentative image 530 a to another image 530 a′ associated with thefirst representative image 530 a for which the focus is formed on thesecond figure.

Accordingly, the user can convert a plurality of representative imagesto different images with a changed focus using a graphic image containedin the fifth control image 650, and easily perform a focus change on aplurality of figures.

A control method of sharing the plurality of representative images willbe described with reference to FIG. 8C. FIG. 8C illustrates the displayunit 151 on which a plurality of representative images including animage for which the focus is adjusted on the first and the second figureare displayed at once.

The controller 180 controls the display unit 151 to track a figurecontained in the plurality of images based on a touch input applied toan icon for sharing the plurality of images, and display a sixth controlimage 660 containing the information of the tracked figure.

The sixth control image 660 may include a graphic image corresponding toeach figure, and the graphic image of the selected figure may bedisplayed at an upper portion of the sixth control image 660.Furthermore, the sixth control image 660 may include a figure containedin the representative images and a graphic image of the associatedfigure.

The controller 180 may share at least one of the plurality ofrepresentative images for a figure due to the control command based on acontrol command applied to the graphic image.

FIGS. 9A and 9B are conceptual views for explaining a control method ofdisplaying images at different angles for which the objects areacquired.

Referring to FIG. 9A, the camera may include a plurality of imagesacquired at different angles at a substantially same time. Furthermore,the controller 180 controls the display unit 151 to display an imageacquired at a preset angle among the plurality of images as arepresentative image.

According to the present embodiment, the controller 180 controls thedisplay unit 151 to display another image 541 acquired at a differentangle at a substantially same time based on a touch input applied to thedisplay unit 151 that displays a representative image 541.

When a control command for adjusting an angle at which the object isacquired is applied, the controller 180 may track a figure contained inthe representative image 540, and track the gaze of the tracked figure'seye. The controller 180 displays a seventh control image 670 to beoverlapped with a figure contained in the representative image 540 toindicate the tracked figure. For example, the seventh control image 670may be formed with a symbol displayed on each figure's face.

The controller 180 controls the display unit 151 to change the fourthcontrol image 640 to another image 641 so as to correspond to thefigure's gaze based on a touch input applied to the seventh controlimage 670 indicating the one figure. In other words, the another image641 corresponds to an image captured in the direction of facing theselected figure.

When the selected figure looks down in the fourth control image 640 asillustrated in FIG. 9A, the another image 641 corresponds to an imageacquired in the downward direction.

However, when there is no images acquired in the direction of facing theselected figure's gaze (for example, a camera according to the presentdisclosure captures an object within a preset angle range, and thus acapture image at an angle other than the preset range may not beformed), the controller may control the display unit 151 to display animage captured in the direction closest to the facing direction.Furthermore, in case of the foregoing, the controller 180 may controlthe display unit 151 to display information in which there is no images(corresponding to the selected figure's gaze) acquired from the facingdirection. Furthermore, the controller 180 may control the display unit151 to display the representative image 540 in a bounce effect fordisplaying in such a manner that an image captured in the closestdirection is returned again to the representative image 540.

According to still another embodiment, when the gazes of a plurality offigures are converged to one figure (or another object), a figure at alocation where their gazes are converged may be defined as the selectedfigure. In other words, when two figures look at one person asillustrated in FIG. 9A, the controller 180 controls the display unit 151to display an image according to the figure's gaze.

Though not shown in the drawing, the controller 180 may control thedisplay unit 151 to convert a region containing the selected figure topart of another image acquired at a different angle.

For example, when a distinguished touch input (for example, a long touchinput) is applied to the seventh control image 670 displayed on theselected figure as illustrated in FIG. 8A, the controller 180 controlsthe display unit 151 to display part of an image acquired in thedirection of facing the selected figure's gaze instead of a regioncontaining the selected figure.

However, the controller 180 may control the display unit 151 to displaya graphic image containing the information of the tracked figure (referto FIG. 7A), and control the display unit 151 to display another imagebased on the selected figure's gaze based on a touch input applied tothe graphic image.

In other words, there is no limit in a control method for selecting atleast one of the tracked figures contained in a representative image.

In other words, the controller 180 may control the display unit 151 tocombine and display the representative image with part of another imageassociated with the representative image.

Accordingly, the user may convert and display a plurality of imagescaptured at different angles at the same time to images captured at hisor her desired angle or partially combine and display them.

On the other hand, though not shown in the drawing, when a controlcommand for sharing the selected figure and the representative image 540is applied and the selected figure is contained in the representativeimage 540, the controller 180 may control the display unit to share theanother image 541.

In other words, when performing a function associated with a figurecontained in the representative image 540, the controller 180 maycontrol the mobile terminal to use the another image 541 acquired at anangle corresponding to the figure's gaze.

FIG. 9B illustrates a control method of displaying an image acquired ata different angle according to another embodiment.

Referring to FIG. 9B, the display unit 151 displays an eighth controlimage 680 to be overlapped with the representative image 540. The eighthcontrol image 680 indicates an angle at which the camera has acquired anobject. The eighth control image 680 may be formed with two linesegments crossed with each other. Accordingly, the user can recognize alimited range of angles at which associated images are acquired.

Referring to FIG. 9B, the controller 180 controls the display unit 151to display another image 541 displayed at a different angle based on atouch input applied along the eighth control image 680. For example, thecontroller 180 may control the display unit 151 to display another imagecorresponding to a time point at which a touch input consecutivelyentered to the eighth control image 680 is released.

Furthermore, the controller 180 may control the display unit 151 toconsecutively convert and display a plurality of images acquired by theconsecutive angle based on a touch input consecutively applied to theeighth control image 680.

Though not shown in the drawing, the controller 180 may control thememory 160 to store the another image 541 in a separate manner, or storethe another image 541 as a representative image of the associatedimages.

According to the present embodiment, the user can receive a plurality ofimages captured at different angles for the same object, and more easilyreceive an image captured at his or her desired angle by a touch inputapplied to the display unit 151.

FIGS. 10A and 10B are conceptual views for explaining a control methodof changing a capture angle for which a plurality of representativeimages are acquired when the plurality of representative images aredisplayed at once on the display unit 151.

A control method of displaying an image based on the selected figure'sgaze by the selection of the tracked figure will be described withrespect to FIG. 10A. Referring to FIG. 10A, the controller 180 controlsthe display unit 151 to track a figure contained in the plurality ofrepresentative images and display an indicator on the figure.

When a touch input is applied to one region of the display unit 151 thatdisplays the figure, the controller 180 selects the figure to track thefigure's gaze. The controller 180 controls the display unit 151 todisplay another image acquired in the direction of facing the selectedfigure's gaze, and associated with the representative images,respectively.

For example, the selected representative image 550 containing theselected figure is converted to another image 551 for which the sameobject is captured at a different angle at a substantially same time asthe selected representative image. Furthermore, the rest representativeimages excluding the selected representative image 550 among theplurality of representative images are also converted to differentimages captured in the direction of facing the selected figure's gazeand associated with the representative image.

In other words, the user can select a plurality of figures contained ina plurality of representative images to convert a plurality of imagesdisplayed on the display unit 151 at the same time according to thefigure's gaze.

Accordingly, the user can more easily receive images for which differentobjects are captured at different time points at one angle.

A control method of converting a plurality of images according toanother embodiment will be described with reference to FIG. 10B.Referring to FIG. 10B, the controller 180 controls the display unit 151to display a ninth control image 690 for converting a plurality ofrepresentative images for which different objects are captured atdifferent time points to other images associated with eachrepresentative image and captured at different angles.

The ninth control image is formed with a plurality of line segments. Theline segment indicates an angle at which an object can be captured bythe camera 121, and an indicator point indicating an angle at which arepresentative image currently displayed on the display unit 151 iscaptured may be contained in the line segment.

For example, the indicator point may indicate an angle at which theselected representative image 550 selected by the user's touch inputfrom a plurality of images displayed on the display unit 151. Theindicator point is displayed on a line segment of the ninth controlimage 690. In other words, the plurality of representative images maycorrespond to images captured at different directions.

The controller may control the display unit 151 to move the indicatorpoint to another location on the line segment based on the user's touchinput applied to the display unit 151.

The controller 180 controls the display unit 151 to display anotherimage associated with a plurality of representative images,respectively, captured at an angle corresponding to the moved indicatorpoint.

Furthermore, though not shown in the drawing, the controller 180 maycontrol the display unit 151 to consecutively convert a plurality ofdifferent images based on the user's touch input consecutively appliedto the ninth control image.

Accordingly, the user can receive a plurality of images displayed on thedisplay unit 151 at the same time as images acquired at the same anglebased on the camera 121.

Though not shown in the drawing, the controller 180 may control thememory 160 to store the plurality of concurrently converted images atonce based on the user's additional control command.
